Question

Quizplus · Accepted Answer

Fossils are the remains or traces of organisms that have been preserved in rocks. Specimens of rock strata that show these preserved remains of earlier organisms and their progressive changes are called fossils. Evolution refers to the process of how species change over time, but it is not the correct term for rock strata with fossils. Timelines and outcroppings may be related to geology, but they do not specifically refer to rock strata with preserved fossils.
